  • Publication number: 20190231640
    Abstract: A CPR feedback system, software and methods are provided. A top height sensor can be used to track the height of the patient's chest during the CPR chest compressions, by detecting a top aspect of its location. A depth module may generate, from a detected top aspect, a depth value for a depth reached by a current compression. A counter may determine a compressions number, e.g. for the current compression. A memory may store a depth variable that can return different target values for the target depths of individual compressions. A user interface has an output device that may output an indication for the rescuer, which reflects how well the depth value of the current compression matched a corresponding target value for it. The target values may be set so as to follow a preset profile, or change according to optional measurements of force and other parameters.

  • Patent number: 10365158
    Abstract: A spectral imaging device (12) includes an image sensor (28), an illumination source (14), a refractive, optical element (24A), a mover assembly (24C) (29), and a control system (30). The image sensor (28) acquires data to construct a two-dimensional spectral image (13A) during a data acquisition time (346). The illumination source (14) generates an illumination beam (16) that illuminates the sample (10) to create a modified beam (16I) that follows a beam path (16B) from the sample (10) to the image sensor (28). During the data acquisition time (346), the control system (30) controls the illumination source (14) to generate the illumination beam (16), and controls the image sensor (28) to capture the data. Further, during the data acquisition time (346), an effective optical path segment (45) of the beam path (16B) is modulated.

  • Publication number: 20190131769
    Abstract: An assembly (14) for analyzing a sample (15) includes a detector assembly (18); a tunable laser assembly (10); and (iii) a laser controller (10F). The detector assembly (18) has a linear response range (232) with an upper bound (232A) and a lower bound (232B). The tunable laser assembly (10) is tunable over a tunable range, and includes a gain medium (10B) that generates an illumination beam (12) that is directed at the detector assembly (18). The laser controller (10F) dynamically adjusts a laser drive to the gain medium (10B) so that the illumination beam (12) has a substantially constant optical power at the detector assembly (18) while the tunable laser assembly (10) is tuned over at least a portion of the tunable range.

  • Publication number: 20190117501
    Abstract: A Cardio-Pulmonary Resuscitation (“CPR”) device can include a compression mechanism configured to perform successive CPR compressions on a chest of a patient, the compression mechanism including a piston and a contact member attached to the piston, the contact member configured to make and maintain contact with the chest at a first position and a first orientation. The CPR device can also include a controller communicatively coupled with the compression mechanism, the controller configured to: receive at least one input; determine whether the piston should be adjusted based on the at least one input; and responsive to a determination that the piston should be adjusted, cause the piston to move so that the contact member makes and maintains contact with the chest at a second position and a second orientation.

  • Publication number: 20180289976
    Abstract: A wearable cardioverter defibrillator (“WCD”) system includes a support structure that can be worn by a patient, and a defibrillator coupled to the support structure. An ECG input, rendered from an ECG of the patient, may meet a primary shock criterion. One or more sensor modules are further provided, which are worn by the patient at different times. The sensor modules may monitor different physiological parameters of the patient, and transmit signals about them. The WCD system further has a multi-sensor interface to receive the transmitted signals, and a processor to determine from them whether a secondary shock criterion is met. If both the primary and the secondary shock criteria are met, the decision is to shock. The signals increase specificity of the detection, while the patient can wear different modules depending on context.

  • Publication number: 20180160939
    Abstract: A capnograph system may be used together with a ventilation system for a patient. The capnograph system may include a capnography module with a carbon dioxide detector, which may generate a carbon dioxide signal responsive to an amount of carbon dioxide detected within an air path of the ventilation system. A monitoring circuit may further detect a pressure within the air path. A processing component within the capnography module may generate a pressure signal responsive to the pressure detected in the air path. The pressure signal, alone or in combination with other signals such as the carbon dioxide signal, may be used to detect spontaneous breaths of the patient.

    Abstract: An analysis assembly (12) for analyzing one or more physiological parameters of a person (10) comprises a sensor assembly (14) and an analyzer (16). The sensor assembly (14) includes a sampler (218) that collects a sample (220) from the person (10); and a signal generating apparatus (222) that directs a mid-infrared light beam (232) toward the sample (220) and performs spectroscopy on the sample (220) to generate a signal (215) that is based at least in part on the one or more physiological parameters of the person (10). The sampler (218) and the signal generating apparatus (222) can be positioned less than approximately one meter from the person (10) while the sample (220) is being collected and spectroscopically scanned to generate the signal (215).
